Tinnitus Functional Index (TFI) Subscale: Cognitive
- Title of study: What changes are reflected in the TFI Subscales as individuals progress through the CBT4T process?
- The study uses 24 sets of Tinnitus Functional Index (TFI) Outcomes
- Each person joining CBT4T completes a Tinnitus Functional Index initially, repeated and compared at Stages 4, 6, 7 and/or 8
- Data for this study is provided by individuals using the CBT4T programme during 2026 who have completed at least up to Stage 4
- Of the 24 sets of Outcomes, 15 are current and actively participating in the CBT4T programme at the time of publication (August 2026); 9 have completed
- Individual qualitative feedback and evaluations (and individual TFI results) can be viewed in Reviews
Note: Flexibility is built in to CBT4T so that every person uses the process at a pace that suits their own needs and responsibilities. This means that some individuals progress more quickly / more slowly through the Stages than others. View CBT4T Enrolment
PART ONE
- Average Percentage Improvement (API) Outcomes for TFI Cognitive Subscale: 24 sets of Outcomes combines CBT4T Current / active group (15) and CBT4T Completed group (9)
- Average Percentage Improvement (API) for 9 sets of TFI Cognitive Subscale results: the CBT4T Completed group (9) according to their initial TFI category at CBT4T enrolment

Tinnitus Functional Index (TFI) Subscale Q 7-9: Cognitive
Conceptual content for the Cognitive subscale covers:
- Cognitive interference
Preceding each question is "Over the past week..."
- Q7: Your ability to CONCENTRATE?
Did not interfere > 0 1 2 3 4 5 6 7 8 9 10 < Completely interfered
- Q8: Your ability to THINK CLEARLY?
Did not interfere > 0 1 2 3 4 5 6 7 8 9 10 < Completely interfered
- Q9: Your ability to FOCUS ATTENTION on other things besides your tinnitus?
Did not interfere > 0 1 2 3 4 5 6 7 8 9 10 < Completely interfered

PART TWO: Average Percentage Improvement (API) for 9 sets of TFI Cognitive Subscale results: the CBT4T Completed group (9) according to their initial TFI category at CBT4T enrolment
Tinnitus Functional Index (TFI) categories:
- Category 5: 73-100% (very big problem)
- Category 4: 54-72% (big problem)
- Category 3: 32-53% (moderate problem)
- Category 2: 18-31% (small problem)
- Category 1: 0-17% (not a problem)
CBT4T was developed specifically for those with an initial category 4 (54-72%) or 5 (73-100%) Tinnitus Functional Index (TFI). It has proven to be suitable for those with an initial category 3 (moderate problem), but those presenting with an initial category 2 (small problem) TFI are encouraged to consider the CBT4T-6 Module course.
